HOOD LOCK Filed May 12, 1927 fastening devices 2 Patented May 12, 1931 WALTER GEORGE ROBERT-HEINE, 0F DETROIT, MIGHIGAN noon Loox Application filed May 12, 1927. Serial No. 190,663.

The present invention pertains to a novel lock des'i ed particularl for securin the movable i dod elements of an automobile.

The principal object of the invention is to provide a hood lock entirely on the inner side of thehood and frame so that unauthor ized access thereto will not be possible. The operating linkage of the lock extends through the toe board of the vehicle and is there accessible for operation. In the toe board is also provided a lock adapted to fix the linkage in a position which sets the lock-= ing elements in locking position.

By means of adevice of this character the motor is protected against damage by unauthorized persons, and a lower rate of insurance may thereby be made possible. The

a pearance of the .vehicle is improved by t e fact that the locking parts are out of 0 sight, and these parts are of such simple construction that the cost of production is comparatively low. I a

The invention is fully disclosed in the following description and in the accompanying .drawings in which Figure 1 is an elevation of the device in locked position;

Fig. 2 is a similar view showing the device in open position, and w F(Fig. 3 is a plan section corresponding to Reference to these viewswill now be made by use of like characters which are employed 'to designate corresponding parts throughout.

The chassis of the vehicle is indicated in part by the character A and on the chassis are mounted movable hook sections, one of which is indicated by B, and the toe board G in the regular manner.

The lock construction comprising the subject matter of this invention includes a hook 1 secured to the inner surface of the hood section B and preferably at the lower edge thereof. The hook is positioned in such a manner that it preferably extends beyond the lower edge of the member. to which it is secured; Theusual handle 2 at the outer sideof the member B is held by the same hat hold back the hook,

ated by the same rod 8.

and the back of the hook serves to reinforce the portion to which the handle is-joined.

Beneath the hook 1, a latch 3 is pivoted to the chassis A by means of a stud 4. The upper edge of the latch has a partially slot- I! ted flange 3 adapted to receive the hook 4 and abut the same as shown in Fig. 1. In other words the unslotted part of the flange engages thehook and in this position prevents the latter from being raised. A tension spring 5 has one endsecured to a lower corner of the latch and its other end to a bracket 6 fixed on thechassis. This spring tends to retract the latch from the hook or release the locking device presently to be described.

A link 7 which is partially internally threaded as at 7 and pivoted to the remaining corner of the latch 3 by a pin 11 receives in an adjustable manner the lower threaded end 8 of a link which passes through a slot 9 cut through the toe board C. The upper or outer end of the arm 8 is provided with a hinged handle 10 adapted to lie'flaton the toe board when the latch 3 is in lock- {ing position as shown in Fig. 1. -In the opening 9 is fitted a lock 13 having a bolt 13 adapted to enter a slot 12 cut in the up per end of the arm 8 and thus lock the latch in its retaining position. In this adjustment the hood cannot be raised by an unauthorized person, for the bolt 13' must first be withdrawn by the use of proper key to the lock 13.

The latch is released from the hook by 35 withdrawing the bolt in the manner indicated and pulling the link 8 upwardly to the position shown in Fig. 2. Below the slot 12 a notch 14 is cut in the arm 8 and is adapted to receive the lock 13.and thus to support the arm in the raised position which corresponds to the release -position of thelatch B.

Two or more hooks 1 may be provided if the hood section B is unusually long. The latches provided therefor may be oper- -Although a specific embodiment of the invention has been illustrated and described, it will be evident that various alterations in the details of construction may be made without departing from the scope of the invention as indicated by the appended claims.

What I claim is Y 1. In combination with the chassis, hood and toe-board of an automobile, a hook carried by said hood, a latch pivoted to said chassis and liaving one end adapted to engage said hook, a spring connecting, said latch to the chassis and adapted to bring said latch into engagement with the hook, and operating means extending from said latch through said toe-board, said operating means being provided with a notch to engage said toe-board to maintain said latch in one of its positions of adjustment.

2. In combination with the chassis, hood and toe-board of an automobile, a hook car-- ried by said hood, a latch pivoted to said chassis and having one end adapted to en gage said hook, a spring connecting said latch to the chassis and adapted to bring said latch into engagement with the hook, an operating link extending from said latch through said toe-board, akey-controlled lock mounted in said toe-board and having a bolt, said link having a slot adapted to receive said bolt when projected, and a notch below said slot to engage said lock to maintain said latch in one of its positions of adjustment.

3. In combination with the chassis, hood and toe-board of an automobile, a hook carried by said hood, a latch pivoted to said chassis, adapted to engage said hook, an operating link extending from said latch through said toe-board, a key-controlled lock mounted in said toe-board and having a bolt, said link having a notch for engaging a portion of said lock to maintain said latch in one of its positions of adjustment'and having a slot adapted to receive said bolt when projected.

4. In combination with the chassis, hood and toe-board of an automobile, a hook carried by said hood, a latch pivoted to said chassis, adapted to engage said hook, an operating link extending from said latch through said toe-board, a key-controlled lock mounted in said toeboard and having a bolt, said link having a notch adapted to receive said bolt when projected and also a notch beneath said slot adapted to be fitted over said lock, whereby tomaintain said link and latch in one of their positions of adjustment.

In testimony whereof I afiix my signature. A

WALTER GEORGE ROBERT HEINE.
